IX or SAID COMBINATION ORGAN-STOP ACTION.

. Application filed June 11,

To all whom it may concern:

Be it known that I, ELEK LOUIS, a citizen of Hungary, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Combination Organ Stop Actions, of which the following is a specification.

The present invention relates to electrically operated organs, and has for its main objectto provide a. stop'mechanism, which is simple in construction, and efiicient in operation. o

lVith these and other objects in view, which will more fully, appear as the nature of theinvention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of theseveral parts and details of construction within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages One of the many possible embodiments of the invention is illustrated, in the accompanying, drawings, in which I Figure 1 is a side elevation, partly-in section, of a portion of an organ, including a stop mechanism constructed in accordance with the present invention; Fig. 2 is a section taken on line 2-2 of Fig.1; Fig. 2

is a section taken on line 2 2 of Fig. 1;

- Fig. 3 is a vertical section taken through the wind-chest of the organ, showing one of its pipes; Fig. 4 is a rear elevation of one of the valves controlling the communication betweenthe windchest and organ pipes; Fig. 5 is a perspective view of a rocker, forming part of the stop mechanism, and Fig. 6 is a diagram of the electric circuits of the device.

In the drawings, the numeral 10 indicates a frame or support, on which is ,sli dably disposed a stop handle 11, the inner end of which is pivoted at 12 to one end of a lever 13. This lever is fulcrumed at 14, intermediate its ends, to the frame, and is connected by-a rod 15 with a horizontally disposed stop bar 16, the front end of which is pivoted at 17 to a link 18, thelatter being fulcrumed at 19 to the organ frame.

. Specification of L ettcrs Patent. Pat t Ma 1919. Serial No. 303,347.

To the rear end of the bar 16 is pivoted at 20 a contact lever 21, fulcrumed' at 22 to the frame and carrying a contact piece 23, which is adapted to bridge thegap between two stationary contact points 24 of an electric circult 25, into which is inserted a mechanism for actuating a slide or valve. This mechanismiis not shown in the drawings as 1t iswell-known and does not form part of the present invention H The stop-bar is provided with. a longitudinal slot 26,.within which is disposed. a rocker 27, shown in detail in Fig. 5 of the drawings. The rockeruis pivoted at 28 to the bar, and comprises a flat body including two Jangularly disposed portions 29 and .30, arranged in such a manner that, when thereto a weight 32, servinguto hold the rocker firmly in either one ofits positions. The rocker 1s furthermore provided with an aperture 33, through which extends a pin -34,qcarried by the stop-bar, said pin serving to limit the movement of the rockerin either direction.

. For' setting the rocker, for purpose hereinafter to be described, there is provided a setting-bar 35, said bar being. disposed in operative relation to the said rocker below the same. This bar is hired to a lever 36, that is fulcrumed, intermediate its ends, at 37 tothe organ frame and is connected by a rigid wire 38 with a lever 39, the latter being fulcrumed at 40 to the frame. To the free end of this lever (is fixed an electromagnet 41, actuating an armature 42, that is carried by an arm 43. This arm is pivoted at its upper end to the lever 39 and provided at its lower end with a forwardly extending lug 44. Immediately above this lug is disposed one end of a bar 45, that is fulcrumedat' 46 to "the organ frame and carries at its other end anarmature 47, actuated by an electro-magnet 48. A spring 49,

bearing against the setting-bar 35, has a spectively, to the frame below the said slidin -g bar in oper tive relation to the rocker 27. These fans are each provided. adjacent their respective pivots with a lug 54, extending toward each other and pivoted to a downwardly projecting rigid wire 55, that is fixed to a lever 56. This last-mentioned lever ext-ends horizontally in parallel relation to the lever and is provided with a depending rigid wire piece 67 carrying adjacent its upper end an armature 58. This armature actuated by an electro-magnet 59 on the lever 56, while the lower end of said wire piece 57 is provided with. an inwardly bent lug 60, in proximity to which is dis posed toe free end of the bar 45 above reterred to. Springs are interposed between the fans 50 and 51.

The electro-magnet 41 is inserted into an electric circuit 61, and the electro-magnet 59 into an electric circuit 62. Both of these circuits contain the electromagnet 48 and a source of electric energy 63, common to both circuits. The circuit 61 is controlled by a switch 64 and the circuit 62 by a switch 65, the arrangement being such that, when the circuit 61 is closed, the electro-magnets 41 and 48 are energized, and, when the circuit 62 is closed, the electro-magnets 59 and 48 are energized.

The switches 64 and 65 are located below the keyboard 66 of the organ. Each key 67 on this board carries an electric conductor 68, that acts as a switch, overlapping the gap between contact points 69 of: an electric circuit 70, into which is inserted an electromagnet 71. The armature 72 of this electro-magnet is carried by a stem 73, that is pivoted to the wall of the wind-chest 74 of the organ. This stem is provided at its free end with a disk valve 75, controlling the communication between the interior of the wind-chest and the respective organ pipe 7 6.

The operation of this device is as follows z-In Fig, 1 of the drawings the stop bar 16 is in its oil position and the portion 99 of the rocker projects below the un derface of the stop bar 16. If it is intended to shift the stop bar to its on position, in which the contact piece bridges the gap between the contact points 24, the electric circuit 62 must be closed. lVhen this circuit is closed by operating the switch 65, the electro-magnets 59 and 48 are energized. As the magnet 59 is energized, it attracts the armature 58, thereby swinging the wire piece 57 so that its lug 60 is brought into the path of the bar 45, the latter being caused to swing around its fulcrum 46 in the direction of the arrow shown in Fig. 2 of the drawings, when the armature 47 is attracted by the electro-magnet 48. Vhen the bar 45 swings in the direction indicated, it

causes the lever 56 to move downwards other. The Fan. I30, abutting against the portion 29 ol the rocker, sl'uits, due to the movement mentioned, the stop-bar lo in the direction of the arrow shown in Fig. 1. o if the drawings, imparting a, corresponding motion to the contact-d voi- 21., whereby the gap between the stationary contact points 5221; is bridged.

.is soon as the electric circuit is pcned, the wire piece 5'? swings haclz; to its normal position, the springs 56' causing the other elements associated with the said wire piece to move to the normal position, shown in Fig. 1 01" the drawings.

If it is desired to shift the stop-bar from its on position to its off position, and the portion 29 of the rocker projects below the underface of the stop-bar, first the said rocker must be swung around its pivot so that its portion 30 projects below the stopbar. This is accomplished by closing the electric circuit 61, whereby the electro-magnets 41 and 48 are energized. By this op eration, the wire piece 38 moves with the lever 89 and causes the setting-bar to move upwards, whereby the rocker is swung around its pivot point 28, so that the portion 30 thereof projects below the undcriliace oi? the stop-bar. The electric circuit 61. then opened, the spring 49 returning the elements to their normal positions. hen now the electric circuit (32 is closed, the fan 51 moves the stop bar in the direction opposite to the arrow shown in l ig. 1 of the drawings.

lVhat I claim is 1. In a combination organ sto 'a-action, the combination with a horizontally disposed. shil'table stop-bar, of a rocker pivotally mounted 011 said bar having two distinct portions extending at an angle to each other, either one of said portions being adapted to project below the undertace of said her when the other is above said underiface, a shilftable bar for settin said roc 1 extending levers, one of said lo 1 connected with said settingd other one with said fans. elc one carried by the free end 01 ea levers, said, magnets being in h n Quits, a downivzu'dly extending bar upon each oil? said levers provided with an armature in operative relation to the respective electro-magnet, said downwardly extending bars being each provided with a lug, a bar having one of its ends in operative relation to said lugs, an armature carried by the other end of said last-mentioned bar, and an electro-magnct actuating said lastonentioncd armature, said last-ment oned elcctro-magg the other one with said fans, electrocombination with a horizontally disposed shiftable stop-bar, of a rocker pivotally mounted on said bar having two distinct portions extending at an angle to each other,
